A brief review of steel-deck-reinforced floor systems and resulting failure modes is presented, followed by the development and evaluation of design equations for one-way shear-bond capacity. A linear regression of pertinent strength parameters was utilized to fit potential design equations to experimental data. Results of three of several possible equations are given; these are based on parameter grouping from 353 specimens of various types tested at Iowa State University and 151 proprietary tests conducted by steel-deck manufacturers. Example regression plots pertaining to slab elements for six different steel deck configurations were developed. Effects of shoring and gage thickness are considered. The preferred design equation was obtained from a relationship for shear design in the 1971 ACI Building Code.
